Just because I got a impression that 'there is a design policy that libvirt should
work only with active domain' after talk with redhat guys.

If it's allowed, it's best.

No problem with that.

Off topic)

BTW, with 

%virsh vcpupin --domain ID --vcpu 0 --cpulist 0
%virsh vcpupin --domain ID --vcpu 1 --cpulist 1
vcpu '0' will be on '0' and vcpu '1' will be on '1'.

How to describe this in XML format ?

<vcpu cpuset="0-1">2</vcpu>

will allow vcpu0 onto 0 or 1, vcpu1 onto 0 or 1. Right ?

Thanks,
